BPH – Tut # 2 Fluid Mechanics – University of Technology‚ Sydney – Engineering & IT Tutorial # 2 – Questions and Solutions Q.1 For the situation shown‚ calculate the water level d inside the inverted container‚ given the manometer reading h = 0.7 m‚ and depth L = 12 m. Q.2 (from Street‚ Watters‚ and Vennard) The weight density γ = ρg of water in the ocean may be calculated from the empirical relation γ = γo + K(h1/2)‚ in which h is the depth below the ocean surface‚ K a constant‚ and

Cost‚ Volume‚ and Profit Formulas Heather Jauregui University of Phoenix of Axia College “The Cost-volume-profit (CVP) analysis is the study of the effects of changes in costs and volume on a company’s profits.” (Kimmel‚ P.‚ Weygandt‚ J.‚ & Kieso‚ D. 2003) The analysis is used to maximize efficiency in a business. In order to be effective the CVP analysis has to make several assumptions. These assumptions are that the costs can be fitted into either fixed or variable categories. The

Attention deficit hyper disorder also known as ADHD‚(Shea 5) is a very common disorder. ADHD is a neurobehavioral disorder‚(Shea 7) about nine percent of all American children ages three to seventeen have been diagnosed‚ and four percent of adults.(Shea 8) Some symptoms of ADHD include impulsiveness‚ inattentiveness‚ and hyperactivity. (Shea 6) Though ADHD is very common‚ it is hard to diagnose. There is no medical test which can diagnose ADHD. It takes the help of parents‚ teachers‚ and doctors

Midterm Exam II Solution‚ ME 342 Fluid Mechanics (Spring 2013) 1. Consider a steady‚ incompressible‚ y=+h b viscous flow of viscosity due to y a pressure gradient x inside a channel of two fixed u=u(y) plates at a distance of 2h‚ as shown in the figure. Neglect a gravity effect. The channel width y=h b is W and it is very long compared to the channel length L (i.e.‚ W>>L) so that it is still valid to assume that the channel flow is a two-dimensional plane flow ( ) and an axial flow (v = w = 0)

Change in Pressure and Different Depths in a Static Fluid Lab Marcus Uchaker MET: 2050 January 26‚ 2012 Purpose: The purpose of this lab is to devise a correlation between that of the data we have collected from our experiment and compare it to that of theory. In this experiment 3 different tests were done in order to test this theory. The first test was to tie a balloon on the end of a manometer and measure the pressure at different depths in a large beaker filled with water. The next

Experiment 1 Fluid Flow In A Smooth Pipe Abstract In this experiment‚ three variable flow meters are used to alter the flowrate. Changes in pressure drop due to the change in flowrate are then observed from the three pressure gauges that can measure pressure at different range and recorded. The shift from laminar flow to turbulent flow is seen from the results recorded‚ but it is observed more clearly from the water-soluble dye experiment that was carried out by the demonstrator. Laminar flow
